Multimorbidity and healthcare utilization among early survivors of pediatric cancer.

Early survivors of pediatric cancer are at increased risk of experiencing chronic conditions; however, little is known about the morbidity burden in this population. In this observational cohort study of commercially insured pediatric cancer survivors in the United States (2009-2014), we find that 22.5% of survivors had one chronic condition, and 36.3% had multiple. Compared with survivors without chronic conditions, the presence of multiple conditions significantly increased the odds of an emergency department visit by 70% (odds ratios [OR], 1.7; 95% confidence interval [CI], 1.4-2.1) and of a hospitalization almost four-fold (OR, 3.8; 95% CI], 2.5-5.5). Findings are important for informing pediatric survivorship care plans in the years following completion of therapy.
